# CAMEO+ domain codes

> What each non-political CAMEO+ code means — the nine domains GDELT Cloud adds to CAMEO.

<Note>
  **This page is the DICTIONARY.** It says what each code MEANS — the definition the coder applies,
  and what the code includes and excludes — so you can decide whether it is the right one. For the
  full value list and how the codes nest, use the
  [complete event taxonomy](/reference/taxonomy-complete).
</Note>

CAMEO stops at politics. These **9 domains** and **56 codes** are the GDELT Cloud extension covering everything else that is a discrete event: crime, the economy, corporate action, technology, infrastructure, environment, health, demography and information.

Each domain uses a compact `<2-letter><ordinal>` code, so the first two characters identify the domain. Filter with `GET /api/v2/events?family=cameoplus&cameoplus_domain=<domain>` or on a specific `code`.

<Warning>
  **Goldstein does not apply here.** `goldstein_scale` carries meaning only for CAMEO POLITICAL and for the conflict family. Every other domain stores `0.0` by schema instruction — treat it as *not applicable*, never as neutral. `significance` is the cross-domain ranking number.
</Warning>

<Info>
  **Codes are a published contract.** A code string is in the warehouse and in customer queries, so codes are added and deprecated — never renamed. Filtering on one is safe to hard-code.
